Commands for Status Monitoring and Statistics
configure sys-recovery-level
For the “ i ” series switches:
configure sys-recovery-level [none | [all | critical] [msm-failover |
reboot | shutdown | system-dump [maintenance-mode | msm-failover | reboot |
shutdown]]
For the “ e ” series switches:
configure sys-recovery-level [none | [all | critical] [reboot ]
Description
Configures a recovery option for instances where an exception occurs in ExtremeWare.
Syntax Description
Default
None
Usage Guidelines
This command is used for system troubleshooting. If the system fails before the switch is booted, the
switch automatically starts the console and allows access to the system to view the logs or debug the
failure. You can also configure the system to respond to software failures automatically. You must
specify one of the following parameters for the system to respond to software failures:
•
none
—No action is taken when a task exception occurs.
•
all
—The system will reboot or shut down if any task exception occurs.
•
critical
—The system will reboot or shut down if a critical task exception occurs. Critical tasks
include the tBGTask, tNetTask, tEdpTask, and tESRPTask.
none Configures the level to no recovery. No action is taken when a task exception occurs; there is no
system shutdown or reboot.
all Configures ExtremeWare to log an error into the syslog and either shutdown or reboot the
system after any task exception occurs.
critical Configures ExtremeWare to log an error into the syslog and either shutdown or reboot the
system after a critical task exception.
msm-failover Triggers the slave MSM to take over control of the switch if there is a software exception on the
master MSM.
NOTE: This option is available only on BlackDiamond switches.
reboot Reboots the switch.
shutdown Shuts down the switch.
NOTE: This option is available only on “i” series switches.
system-dump Triggers a dump transfer, followed by the specified completion action (reboot, shutdown,
msm-failover, or maintenance-mode). Maintenance mode leaves the switch in whatever state the
dump transfer puts it in. Some subsystems may no longer behave correctly or operate at all after
a system dump. The system-dump option should only be used with assistance from TAC.
NOTE: This option is available only on switches with Ethernet management ports.
